My son is 3 days old now, and I haven't had my milk come in yet? I've starting pumping to stimulate my breast approximately every 3 hours. The baby did well in the hospital with breastfeading only; however I've since I've been home I've suplamented with formula, because I didn't think he was getting enough to eat. I haven't felt an "engorement" and the pump doesn't get anything out not even colustrum. This is my second attempt at breastfeeding, I was unsuccesful the first time, and really want to breastfeed my son. I'm not very stressed about it but would like it to work, shouldn't I have milk by now?
